Vehicle Clutch Repairs Townsville

Is your vehicle clutch starting to wear out at Ian Payne`s Automotive Engineering in Townsville provide vehicle clutch repairs for all car, 4x4/4WD vehicles, light trucks, vans.

We are complete clutch engineering workshop, highly equipped with to perform any clutch repair task, its our workshop other clutch mechanics call to repair the difficult jobs.

How The Clutch Works

The clutch connects and disconnects the engine from the gearbox (transmission) allowing smooth gear change and control of the engine power.

A clutch plate (driven plate) is coated on both sides with a hard wearing high friction material. This is situated between the engine flywheel and a spring-loaded pressure plate. The spring/pressure can be released by depressing the clutch pedal.

While driving, the whole clutch assembly can be turning at very high speeds. To allow a non-rotating clutch pedal to control the rotating clutch assembly a clutch release bearing uses a fork acting on a thrust face.

Clutch - Controlling Engine Torque

The clutch has to transmit the engine power to the wheels allowing the vehicle to move. The torque of the engine is transferred by the clutch system relying entirely on the contact friction between 2 faces. A slipping clutch occurs when the friction is too low (often due to clutch wear) or engine torque is too high (during rapid acceleration)

Controlling Power Transmission via The Clutch - Clutch Slip

The torque capacity (how much power can be transmitted without slipping) depends upon:

• The Coefficient of Friction of the engaging Clutch Faces
• The diameter of the Clutch Plate
• The Pressure or Spring Loading

In order to use greater engine torque in high-performance vehicles, a multi-face clutch may be used compared to the single plate clutch system adopted on most cars.

How A Car Clutch Works With Normal Manual Driving

A car clutch is engaged/disengaged using the leftmost "clutch" pedal.
The clutch pedal is depressed to disengage the engine from the gearbox and drive train while changing gears. Once the gear is selected, the clutch pedal is released and the engine is once-again linked via the drive train
The clutch operation can be actuated by:

• A Mechanical Linkage
  The clutch pedal is connected directly to the clutch assembly via a mechanical linkage such as cable or chain.
• A Hydraulic Clutch
  Depressing the clutch pedal increases pressure in a hydraulic piston coupled to the clutch pedal. The increased pressure is transferred to a secondary piston that operates a lever to engage-disengage the clutch plates
• An electronic clutch - Clutch by Wire
  Sensors detect the position of the clutch pedal electronically and interpret the position using an Electronic Control Unit (ECU) that computes the best way to operate the clutch based upon information relayed from other sensors indicating driving speed, engine speed and so on. The ECU relays information to a servo unit to actuate clutch operation.

Clutch Servicing, Kit Fitting & Repairs

Dual Mass Flywheel Clutch Assembly

Dual-Mass Flywheels are fitted in many light commercial vehicles covering very high mileages requiring regular clutch replacement.

• dual mass flywheels
• concentric slave cylinders
• Self-adjusting cover assembly

Clutch

New clutches fitted to most makes of cars using the recommended clutch kits

Clutch Master Cylinder

Pumping the clutch pedal to disengage the clutch is a classic symptom of loss of hydraulic fluid from the hydraulic clutch system and may be indicative of a leak or ruptured seal in the clutch master cylinder or clutch slave cylinder.

Clutch Slave Cylinder

The clutch fittings that link the clutch slave cylinder to the master cylinder can leak but it's also worth checking the piston seals on the clutch slave cylinder
